I will present the first data release of BVRI light curves for 165 nearby Type Ia supernovae (SNe Ia) from the Lick Observatory Supernova Search (LOSS) along with our analysis. The LOSS observations represent a high-quality dataset that can be used to probe the physics of SNe Ia as well as refine their use as cosmological standardizable candles. Drawing mostly from the LOSS sample, I will discuss our results from an analysis of the rise-time distribution of nearby SNe Ia and its dependence on spectroscopic subtype. In addition, we place constraints on the SNe Ia progenitor system using the earliest photometry epochs to search for signs of interaction with a companion star. I will also present results from a cosmological analysis utilizing the LOSS data which are a significant addition to the number of nearby SN Ia light curves. This research was supported by NSF grant AST-0908886 and the TABASGO Foundation.
